Timothy W. Byrne, President & CEO of USLM (United States Lime & Minerals), has demonstrated a clear selling bias in his recent insider transactions, with no recorded purchases in the latest filings. Over 28 reported trades, Byrne has sold a total of $14.99 million worth of USLM shares while buying $10.81 million, though all buying activity appears to have occurred outside the recent period. His most significant disposals include a $5.69 million sale on December 31, 2025, classified as a derivative transaction (Code A), followed by a $3.15 million open-market sale on September 3, 2025, and a $1.57 million sale on June 5, 2024. Smaller but consistent sales occurred throughout 2024 and 2025, often in clustered transactions on consecutive days, such as the $952,778 and $403,777 sales on February 14, 2024.
Byrne’s activity is concentrated solely in USLM, with no trades in other securities. The pattern suggests a strategic reduction in his position, particularly given the absence of recent buys amid sustained selling. Notably, some transactions were tied to derivative instruments (Codes A, F) or gifts (Code G), but the majority were straightforward open-market sales (Code S). The dollar-weighted volume and frequency of disposals—18 sales in the recent period—indicate a deliberate shift away from accumulation. While the reasons remain undisclosed, the data reflects a consistent divestment trend rather than balanced portfolio management.
